You can export the current year reference data and next year's budget separately from QuickBooks Online (QBO) and merge them in Excel for side-by-side comparison, @PKECharity.
Unfortunately, QBO does not currently have a built-in capability to directly export a side-by-side comparison report for the budget and reference data into Excel. Even so, merging the two sets of data in Excel can help you achieve the comparison you need.
